Guys, I am having a weird issue. Weird but repeatable. I have Jawbone Prime BT headset paired to the SF. If I receive a new notification of ANY KIND while on a call using the headset, the screen immediately goes off, and won't stay on, kind of flashes. The audio on the headset also 'pulses', meaning it cuts in and out, but not randomly, almost like something is going on and off. If I switch to handset, the call is fine but the screen still flashes and the BT disconnects then cuts back in, with the same problem. I have tried with several B headsets of varying quality, and the same issue occurs. Anybody else experience this weirdness? My phone is rooted, de-bloated, and running JT's clean .4. Had the same issue running stock. Is there a better BT stack?
